The freezing-point depression for a given aqueous solution is 0.32 K. The freezing-point depression constant for water is 1.86 K/m. Calculate the molality of solutes in the solution.

The equation for freezing point depression is ΔTf = Kf · m, where ΔTf is the freezing point depression, Kf is the freezing-point depression constant, and m is the total molality of all solutes in solution.

I assume this is a non-ionic solution. See my response to your question above or

dT = Kf*m
You know dT and If, solve for m

m = mols/kg solvent. You know m and kg solvent, solve for mols.

Post your work if you get stuck.

To calculate the molality of solutes in the solution, we need to rearrange the equation: ΔTf = Kf · m.

Given:
ΔTf = 0.32 K (freezing-point depression for the solution)
Kf = 1.86 K/m (freezing-point depression constant for water)

We can substitute these values into the equation and solve for m:

0.32 K = 1.86 K/m · m

To isolate m, divide both sides of the equation by 1.86 K/m:

0.32 K / 1.86 K/m = m

Calculating this expression gives us the value of m, which represents the molality of solutes in the solution.
